A pulley for installation in a pulley mechanism of a Jacquard machine has a shaft, a housing having two flank bodies, which are provided to fasten the shaft, so that this shaft extends substantially between the flank bodies, and a pulley wheel, which is provided to be arranged between the two flank bodies so as to be directly rotatable around the shaft. The shaft, prior to assembly of the pulley, is provided with cavities and/or projecting portions for the post-assembly axial securement of the flank bodies in both axial directions.

Pulley for installation in a pulley mechanism of a jacquard machine

A shed forming device for a weaving machine comprising motion systems consisting of hooks that are moveable up and down, transmission elements to transmit the hook motion to a carrier for warp threads, a first force element to exert a downward-directed force on the carrier, and an energy buffer and a second force element to exert a force on an element of the motion system that results in an upward-directed force on the carrier so that the element is so deformed or displaced that the elements of the motion system are kept under tension.

Shed forming device for a weaving machine

A shed-forming device has elastically deformable selection elements () ()-() which can be placed in an undeformed position or in a deformed position, electromagnetic selectors () which can be actuated in order to place or keep each selection element () in successive weaving cycles in one of said positions, and presenting means () in order to mechanically deform selection elements () in the direction of a selector () in each weaving cycle into a presenting position in which they are kept at a distance from the selector () by a stop (), and also relates to a method for positioning selection elements of a shed-forming device in this manner.

Shed-forming device for a weaving machine

A selection device for a shed-forming device of a weaving machine has an electromagnetic selector () with at least two poles (P), (P), . . . (P) and a selection element (), (); (), (); (), () which is located in a cooperating position with a zone () alongside at least two poles (P), (P), . . . (P) and is retained at a holding distance (A) from this zone (), in which the selector () with each adjacent pole (P), (P) can exert a magnetic force on the zone (), and in which the zone () extends over a distance (Z) that is shorter than the coil length (S), while the holding distance (A) is at least equal to half the positionable length (L) of the selection element.

The invention relates to a Jacquard machine, comprising 2 sets of knifes moving up and down in opposition, which each, at each of their extremities, are taken up in separate knife grids () being driven by a cinematic drive chain (), and each, at one of their extremities (), being guided into a straight motion by means of a 'Watt's linkage' rod system, the height of lift of each of these extremities () of the knife grids () being adjustable, and the knife grids () each at their first extremities () being linked with at least one first driving lever () by means of a first linking rod (), and at their second extremities () being linked with at least a second driving lever () by means of a second linking rod (), wherein per knife grid () one or several elements () of the Watt's linkage rod system are part of the cinematic drive chain (), and the amplitude of the motion of the said extremity () of the knife grid () is adjustable in the cinematic drive chain () before the linking point () between the first rod () and the third rod () of the Watt's linkage rod system with respect to the drive motor.

Jacquard machine

A device for modulating a first rotational motion of an input shaft () to a second, different from the first, rotational motion of an output shaft ()in textile machines has a fixed complementary cam () provided with at least two cam profiles (). At least one cam follower () is linked to the input and the output shafts () and is provided with at least two contact rollers (), each following a different cam profile (), because of which the cam followers ()are performing a rocking motion. The cam profiles ()arc internal cam profiles.
